Recalling the splendid culture of the motherland for 5,000 years and today's brilliant achievements is really mixed feelings. Before the17th century, China's science and technology had been at the leading level in the world. In the communication with the world, China's advanced technology has spread to all parts of the world and made great contributions to the world's scientific progress. Silk, tea, matches, precise values of pi and seismographs were all first invented by China.
Besides the advanced science and technology of the motherland, there are splendid cultural heritages, such as the Forbidden City, Terracotta Warriors, the Great Wall of Wan Li, the Potala Palace in Tibet, and the Mogao Grottoes in Dunhuang. These great miracles are the crystallization of the wisdom of our ancestors, which proves that the ancient working people were so talented and left us such a precious historical legacy. Because of this, ancient China deserved to sit on the throne of one of the four ancient civilizations.
However, with the passage of time, many western countries began bourgeois revolution, and the rapid development of science and technology has left us behind. Therefore, our country has worked hard, struggled and achieved brilliant achievements. Now, our new China has developed in all aspects and its international status has been greatly improved. The development of petroleum industry is the victory of self-reliance of new China. In the early 1960s, China's annual oil output was only1100,000 tons. After hard work, Daqing Oilfield, Dagang Oilfield, Huabei Oilfield, Shengli Oilfield and other large oilfields were built one after another, and China got rid of the embarrassment of "poor oil".
Our motherland has not only made industrial achievements, but also developed rapidly in science. "Two bombs and one satellite" refers to atomic bombs, missiles and artificial satellites. In the early 1960s, only four countries in the world were able to manufacture these nuclear weapons. Because of this, China was constantly threatened by these countries. In order to defend our country, under the leadership of New China, we are determined to develop "two bombs and one satellite" by ourselves. With the efforts of a large number of scientific workers such as Deng Jiaxian and Qian Xuesen, atomic bombs, hydrogen bombs, artificial satellites and missiles were finally developed in a relatively short period of time. When the news that the first atomic bomb of our motherland exploded successfully came out, it shocked the whole world. It is known that a country capable of making atomic bombs,1On April 24th, 970, China successfully launched its first artificial satellite-Dongfanghong-1. Not long ago, Shenzhou-1, Shenzhou-2, Shenzhou-3 and Shenzhou-4 came out, Shenzhou 5 manned spacecraft successfully traveled in space, and Shenzhou-6 manned spacecraft was successfully launched. These achievements tell us.
Ah, motherland, my mother! In your journey to the world, you break through many difficulties and go forward bravely. It is because of your openness and enterprising spirit that you are prosperous and powerful now. Today, when we pay deep respect to the high five-star red flag, we will remember the past of our motherland, because we will take over the torch in the hands of our predecessors and forge ahead to the world!
